Question

我是python的新手。我有一个问题，想寻求答案。有我的课：

class DoSomethingWithList :

    def inputList(self, parameter_list):
       ...

    def deleteSomething(self):
       ...

和

的其余部分

temp = 0

while temp == 0 :

selection = input('input selection: ')
list1 = DoSomethingWithList()

if selection == 1 :  
    RangeOfList = int(input('input range of list : '))
    list1.inputList(RangeOfList) # this is not executed
elif selection == 2 :
    list1.deleteSomething()      # and this too
else : 
    temp = 1

此代码永远循环。未执行list1对象。我在这里看不到问题。对不起，我的英语不好

输入函数读取字符串而不是数字。您应该将if条件从'selection == 1'更改为'selection ==“ 1”'，如下所示

$query = http_build_query([
  'app_id' => 'your-app-id',
  'app_code' => 'your-app-code',
  'searchtext' => '123 Some Address',
]);
$url = 'https://geocoder.api.here.com/6.2/geocode.json?' . $query;
$json = file_get_contents($url);
$details = json_decode($json, TRUE);

var_dump($details);

在if语句python 3中执行类的对象
